Factors to consider when selecting a bore sighting device

Though there are boresighters that are capable of fitting in most of the rifles and guns since they use magnetic cohesion, there are many reasons which might make you not like such kind of boresighter. There are different factors to put into consideration when selecting a boresighter.

Some carry more weight than others, but the final decision rests on your preference and choice. Read through the text below and get yourself armed with the buying information to enhance the performance of your armory.


Type of the boresighter

These can be either

  • Muzzle inserted lasers

These are the boresighter that requires insertion at the muzzle or the gun calibers. It’s economical because it can fit in various firearms depending on the adapter used and the o-ring utilized in the exercise in comparison to cartridge lasers. The only drawback with these kinds of boresighters is that the stem of the boresight may be too long for some short guns.

  • Cartridge boresighters

These are calibers inserted in the chamber of the gun and illuminated when the bolt close. The main drawback of these types is the custom settings making it hard to use in a variety of rifles or guns. These types of boresighters are loaded into the machine just the same way you load a bullet.

Bullet Boresighter

  • Magnetic attachment lasers

These are the best selection since they fit in all the firearms you can think of in the market. Whether it is a short gun or a rifle, they are all covered by the design of this boresighter. Due to this dual capability, they might be a bit expensive, but they will save you a lot in the long run.

It is the best buy option for hunters or professional shooters since you might be using different guns and rifles at various times.

Convenience of use

The boresighter should have the capability to be used on as many rifles or guns as possible. Don’t put too much weight on price as some features which make a boresighter expensive are irrelevant. You won’t require them at all.


Check out the ease with which you can put the batteries in the device, the ease of switching the laser on or off, take note that some of the boresighters have no switch anyway. Lack of switch might be a big put off since you have to keep opening and closing the boresighter to remove the batteries.

Type of laser emitted

There are only two choices when laser color is concerned; there are only green or red lasers. The green lasers are more expensive than the red ones, and they are much brighter to use during the day. Holding all other factors constant, the illumination distance of the laser is what is more important. Based on that fact, red lasers are better.

The size of the laser beam is a big point to consider too since it will be hard to zero in with a laser which has a large windage diameter.

Cartridge boresighters

Battery life

Just like illuminating torches, lasers quality depends on the available charge in the batteries. If you notice the dimming of lights, it is the time to change the battery. The lifespan of the batteries will depend on the frequency of use.

Batteries are readily available in the retail shops and customer stores. However, most of the boresighting devices come with a battery set or even a spare battery at the time of purchase.

Lifespan of the boresighter

They are either made from iron, aluminum, brass, and other metals. However, bearing in mind the sensitivity of the device, you do not want something that will be prone to corrosion. Aluminum is both corrosion resistant as well as easy in handling.

Lifespan Of Boresighter

The lifespan of your boresighter also depends on your level of care exercised while using the device. Take care also not to use the boresighter on your loaded guns; you might blow it off unknowingly.
